Security Camera Extension Cables

How to increase the range of MPX and IP security systems

Lorex by FLIR offers two different types of wired HD security camera systems - Analog MPX and Digital IP. Each type of system uses different technologies to provide high-definition video. The type and length of extension cables you can use depend on the type of system you have.

Digital IP

Digital IP systems use CAT5 or CAT5e ethernet cabling to connect IP cameras to a Network Video Recorder (NVR). This cable simultaneously transmits video to the NVR and provides power to the camera.


Connect Cat5 cable directly to a Network Video Recorder

Extend video and power up to 300ft. 300ft, 200ft, and 100ft Cat5e extension cables are available for purchase from Lorex by FLIR.

PoE switch

Connect IP cameras to a network using a PoE switch and router

Connect cameras to an accessory PoE switch with the help of your router. Add another PoE switch for more distance.


Connect IP cameras directly to your router (power separately)

Extend camera up to 300ft from a router. The camera must be plugged in if the router does not support PoE. *Plug sold separately

Analog MPX

MPX security cameras transmit high-definition analog video over BNC cables (RG59 coaxial) to a Digital Video Recorder (DVR). This siamese BNC cable splits into two ends, one for video and one for power.


RG59 coaxial siamese extension cable up to 300ft / 92m (video and power)

250ft, 200ft, 120ft, and 100ft RG59 siamese coaxial cables are available for purchase from Lorex by FLIR.


RG59 coaxial extension cable up to 800ft / 242m (video only)

Extend the video signal up to 800ft using a single run of RG59 cable. Longer cable runs are available from building supply stores.*


Attach a BNC coupler to connect two separate BNC extension cables

Use a BNC coupler to connect two 60ft or two 100ft cables. The camera may have to be plugged into a power source.

*The extension cable must be a single stretch of cable between the DVR and camera. You cannot connect multiple extension cables to each other.
